Importing information from a webpage into an app.

I honestly just want know the best way to do this. I understand RSS feeds and have made a RSS reader but that doesn't seem to do what I want at all.

I want to build an app that will load stories from Fanfiction.net into the app itself and let me see the stories within the app.

The RSS reader I made would only link you to the stories page, then opening a web browser. And it didn't even list all the stories on the site.

I don't have any code linked here because I'm not really in a stage where I need help yet (though I wouldn't be opposed to any code you do link). I more want to know in what direction I should look to figure how to do what I want.

I want accept to every story on the website, the summaries, tags, authors and of course chapter contents, all loadable into the app. I, of course will organize it and store them and all that on my own, I am just not sure how to pull all the data I want in the first place.

Any help would be greatly appreciated.
